ROTARY EXPLOSIVE-ENGINE.

To all lr/mm 1'1.may(o/mom:

lie it known that l, Janus D. linn'Nmga citizen of the Dominion of Canada. and a resident: of Edmonton. in the .Trovinee of Alberta and l hminion of Canada, have invented a new-and Improved Rotary Explosive l lngine, of which the f0ll()\\'l1]! is a full, clear, and exact description.

This invention relates to explosive engines of the rotary type. in which cylinders and reriproeatorv pistons are employed to prodllre the power impulses. the pistons and cylinders operating onthe well-known foureyele prineiple.

The invention has for one. of its objects to improve and implifv the construction and operation of engines of this eharm-ter. so thatgreai power is obtainable. ronsidering the size and weight. as well as smooth running. because of the equal distrihutionot applied 'power and the eounterlmlaneing of the parts. i

Another object is the provision of a rotary engine of the piston and cylinder type wherein the power impulses are applied at a considerable radial distanre froln'the axis of rotation. in order to obtain the maximum power.

An additional object:- is a novel arrangement of evlinders and erank chambers with a simple and e'llertive system for admitting. the fuel eharges to the respective eylinders. the cylinders being so disposed as to he offectively cooled, and the admission and exhaust toi: eaeh cylinder being controlled by a rotaiw valve.

\'\ith-=-t-hese objects in view, and others as will appear as the description proceeds, the invention comprises various novel features of eolistluetioll amt arrangement of parts which will he more fully described hereinafter and set forth with partieuhu'ity in the elain"; appended hereto.

In the accompanying drawings, which illustrate one embodiment of the invention, and wherein similar reference characters are employed to designate eoriespoiuling parts throughout the several 'iews, Figure 1 is a central section of the engine taken transversely to the, axis of rotation and through the pis" tn e 'linder power units; Figs. 2 and 3 are sections through one of the power units n the lines 22 and i-3 of I ig. 1; Fig. 4 is a section through the entire engine on the line 4+4- of Fig. 1; and Fig. 5 is a sii'nila'r section on the line 55 of Fig. 1.

Specification of Letters Patent. Appiication filed May s, 1913.

Patented Apr. 28 1914. Serial no. 765.806.

Referring to the drawings, 1 designates the shaft of the engine, whieh is suitably held stationary, for instance.- hy bearings and between these hearings is rotatably mounted the engine structure.

The engine embodies a plurality of power units A. eaeh consisting of a cylinder 3 and a reriproeatory piston 4, the pistons being of the trunk type. and connected by a eonnerting 'rod .3. with a crank wheel 13,

. which wheel is arranged within a (rank easing 7. The head ofeaeh cylinder has an inlet port H and an outlet or exhaust port 9,

which may open direetly to the atmosphere, or into a suitable mutller, not shown, and for controlling these ports 8 and 9 a. rotary disk valve 10 is arranged in theeylinder in contact with the inner surfaee of the head thereof. This valve has a port, 11 whichis adapted to register with the ports 8 and 9, respeetively. on the suction and exhaust strokes of the piston -t. The disk valve 11 is fastened to the inner end of a stem or rotating shaft 12 passing through an opening 1 3 in the head of the cylinder to carry on its outer end a gear 14 that meshes with a driving gear 15, as clearly shown in Fig. 5. Each crank wheel (3 is mounted on a shaft 16 journaled in bearings 17 in the casing of the engine, and on the shaft 16 is a miter gear 18 which meshes with a miter gear 19 fastened to a shaft- 20 that extends toward the headof thefcylinder of the same power unit for the purpose of driving the inlet and exhaust valve thereof, since on the shaft 20 is mounted 'gear 15-- whielrmeshemwith the gear 1 1 the"val-rem.tith,..this arrangement: the cycle of operation of ea eli power unit is carried out on the well-known 'lour-eyele principle. When the piston moves outward tv on the power stroke it rotates the crank wheel 6. and on the succeeding in stroke the port in the valve 10 registers with the exhaust port 9, so that the eX- ploded' gases are expelled, and on the next stroke a charge of mixture is sucked in through the port 8 in the cylinder head, and port ll in i the valve. During the next stioke the charge is eon'ipressed and ignited at the proper time in the usual manner, the ignition deviees not being shown.

The impulse resulting from the explosions in the various cylinders is utilized to impart rotary motion to the ioweruni'ts as a unitary structure, For this purpose the gear wheels (3 are provided with teeth 21 which mesh-with teeth22 of a gear wheel 23 fixed on the shaft 1: This gear wheel is shown as twice the diameter of the crank gear wheels 6, and a s a 'result each power unit will peri form its complete cycle'of operation during one rotation around the fixed gear 23. Inother words, there will be one impulse imzpar'tedtothe rotary structure during each rotation. In this regardthe engine is in 1Q ultimate efi'ect similar to a two-cycle engine, which gives a power impulse for each rotation of theshaft, but as regards the power.

iltifwiththe fact that the cylinders rotate in the tmgsphe're, causes; an efiective cooling, of lil 'cated'arta p "While. on y four cylinders or power units l have been shown, it is to be understobd that more of them may be employed. Furthermore, the crank wheels 6 may be made larger than those shown; for instance, the same size as the inner gear wheel 23, but in this case each power unit will impart a rotative impulse once in every two revolutions of 5'5 the engine structure instead of one impulse for every revolution in the form of the invention shown. Instead of the crank wheel 13 being stationary and the restof the engine rotatable, the said crank wheel may 0 be mounted to rotate with the engine shaft" while the power units are held stationary, In this arrangement the cylinders can be water cooled whensuch method of cooling is desirable.

Havingthus described my invention, I claim as new and desire to secure by Letters Patent:

l. A rotary engine comprising a central casing, a fixed gear therein, means for admitting fuel mixture to the casing, a plurality of power units carried by the central casing and each consisting of a piston and cylin er and a crank casing communicating with the central casing, a fuel conduit between the crank casing of one unit and the cylinder of an adjacent unit, and a valve controlling each conduit. 2.
